| Abstract [eng] |
Big part of metal processing companies faces with the inefficient labor and low work productivity problem, which can be solved by a system that observes the condition of metal processing machine and tool. In order to create such system, it is necessary to investigate the physical quantities - temperature as close to the work piece, the vibrations resulting from metal processing and the energy consumption of main motor. The aim of masters work: to determine whether the observation of temperature, vibrations and the energy consumption of motor, allows to determinate the state of metal working tools. The research of similar system in market was done in literature review. Also, the sensors, which can measure parameters that are required for analysis of tool state in test conditions, were reviewed and selected. Experimental equipment that allows to measure the temperature close to the work piece, the vibrations arising during processing and to save captured information in medium was created. The analyzer, which is in market and correspond set point requirements, was selected for motor energy consumption research. The research of metal processing machine tool condition was made by using three different diameter (8 mm, 10 mm, and 12 mm) tools and two differnt processed materials – aluminum and steel. It was investigated, if temperature, close to to the work piece, the vibrations resulting from metal processing and the energy consumption of main motor, may be considered as parameters that allows to determinate about tool state. |
